SECTIONAL WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 395,688, dated January 8, 1889.

Application filed July '7, 1888. Serial No. 279,240. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD BIGLEY, manufacturer, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a certain new and useful Improvement in Sectional l-Iot-lVater Heaters, of which the following is a specification.

The object of the invention is to design a sectional hot-water heater with a large heating-surface easily constructed, and in which the fire-surface may be in creased or decreased, as desired, and have its draft regulated without affecting the circulation of warm air between the compartments; and it consists, essentially, of a series of sections, preferably rectangular in shape, and having longitudinal smoke-fines formed between the plates of each section, and a water-space formed between each section, the said water-spaces being connected together by suitable vertical passage-ways arranged as herein described, and extending from a point near the grate to the crown of the furnace, the whole being otherwise constructed and arranged substantially as hereinafter more particularly explained.

Figure 1 is a perspective elevation, partially in section, of my improved sectional hot-water heater. Fig. 2 is a longitudinal sectional elevation through y. Fig. 3 is a cross-section through .2 '10. Fig. i is an enlarged detail showing the style of joint between the sections.

lVith the view of havin as large a fire-surface as possible, and which surface may be easily reduced,if required, I form at each end of the heater a fire-box, A, having a hollow back, B, which connects with the vertical war ter-spaces O on the sides of the heater. An air-space, 1'), is left between the two backs l3 and extends down to a point level with the bottom of the ash-pits F, from which it is separated by the adjustable dampers G. The vertical hollow water-spaces B and C communicate with the horizontal waterspaces H, formed between each section of the boiler, all of which sections above the iire-boxA are composed of a top plate, I, and a bottom plate, J, having flanges a formed around them, the flange around the bottom plate, .l, being recessed, as indicated in Fig. 4, to receive the tongue Z1, formed on the flange surrounding the top plate, I. The joint thus formed between each section must of course be made water-tight. Horizontal smoke-fines K are formed in each section, vertical walls being formed in each section to surround the vertical water-spaces, O, which pass through each section and connnunicate with thehorizontal water-s mces H, as shown.

A central vertical water-space, L, is formed between the two rows of smoke-fines K. This central vertical \vatenspace, L, communicates with the horizontal water-space H; consequently the water which enters through the feed-pipes M into the vertical water-space O circulates through the hollowbacksB, horizontal water-spaces H, and central water-space, L, so that it will come in contact with the entire heating-surface of the boiler before escaping from. the boiler.

It will be noticed that above the water-back B of each fire-box A, I place a damper, N, so that either of the fire-boxes may be cut off without interfering with the satisfactory working of the other fire-box. If both fireboXes are in use, both the dampers N will be opened and the smoke and other heated gases from the two fire-boxes will intermingle and pass up through the opening 0, and thence around through the smoke-dues, as indicated by arrows. If a smaller fire is suflicient, only one of the fire-boxes need be used, in which case the damper N belonging to the fire-box not in use will. be closed, and the smoke and heated gases will pass through the furnace in the same manner.

13 is an ordinary outside damper for regulatin the openings leading into the ash-pits F. By closing the damper G and opening the damper P belonging to the fire-box which may at the time be in use all the air admitted into the ash-pits will pass up through the grate of the said fire-box. Should it be necessary to check the fire in its particular firebox, its damper G is opened, in which case the maj or portion of the air admitted into the said ash-pit through the damper N will pass out of the ash-pit through the damper Ginto the air space D and thence through the smoke-fines K. Each damper G is provided with a suitable crank-rod, Q, indicated in Fig. 1, by which the said damper may be opened or closed, as desired.

As the smoke-fines are made in each section and the water-spaces formed between the sections, 110 smoke-joints are required, the only joint in the furnace being formed around the Water-spaces and 011 the outside of the furnace; consequently any leak will be immediately discovered and cannot occur inside of the heater.

\Vhat I claim as my invention is 1. A hot-water heater composed of a series of sections, preferably rectangular in shape, and having smoke-fines l'ormcd between the plates of the sections, and a water-space between each section, the said water-spaces be ing connected together by vertical passageways arranged substantially as and for the purpose specified.

2. A hot-water heater composed of a series of sections, preferably rectangular in shape, and having longitudinal smokel'lues formed between the plates of the sections, and a waterspace formed between each section, the said water-spaces being connected together by suitable passage-ways arranged as herein described and extending from a point near the grate to the crown of the said heater, substantially as and for the purpose specified.

3. A hotrwater heater composed of a series of sections, preferably rectangular in shape, and having smoke-fines formed between the plates of the sections, and a water-space between each section, connected together by suitable vertical passage-ways, in. combination with a fire-box located at each end of the heater and connected with the smoke-Flues passing through the sections, substantially as and for the purpose specified.

4. A hot-water heater composed of a series of sections, preferably rectangular in shape, and having smoke-fines formed between the plates of the sections, and a water-space formed between each section, the said water-spaces being connected together by suitable Vertical passage-ways, in combination with two fireboxes located at each end of the heater, the said fire-boxes being separated by an airspace through Which the smoke and heated gases pass from the fire-boxes on their Way to the smoke-fines, arranged, as described, in the sections of the heater.

5. A hot-water heater having two fire-boxes separated by an air-space extending to a point where the smoke and heated gases pass into the flues arranged in the heater, combined with the adjustable dampers arranged above the water-backs of each fire-box, substantially as and for the purpose specified.

6. A hotwater heater composed of a series of sections, preferably rectangular in shape, and having smoke-fines formed between the plates of the sections, and a watei space formed between each section, the said waterspaces being connected together by suitable vertical passage-ways extending from a point near the grate to the crown of the fire-box, in combination with two fire-boxes separated by an air-space extending upwardly from the bot-tom of the aslrpit, from which it is separated by adjustable dampers arranged substantially as and for the purpose specified.

'7. A hot-water heater composed of a series of sections having smoke-lines formed in each section and connecting with each other, the said sections being jointed together, so as to form the water-space between each section, substantially as and for the purpose specified.
